14:01:31 <jskarvad> hi
14:03:37 <jskarvad> I uploaded results for F15 to:
14:03:41 <jskarvad> http://jskarvad.fedorapeople.org/pm-tests/
14:04:39 <jskarvad> on my testing machine it seems there is approx 0.5W increase in average power consumption in active idle
14:05:38 <jskarvad> and also some increase in other tests, but to be fair the performance and benchmark score also increases
14:06:02 <jsmith> I saw someone mention that the kernel we're using in F15 has a couple of power-related regressions
14:06:14 <jsmith> I just don't remember who it was who mentioned it, or where :-(
14:06:51 <jskarvad> jsmith: afaik there was published article on phoronix
14:06:57 <jsmith> Ah, that makes sense
14:07:54 <jskarvad> in more detail for the kernel rebuild test different (newer) kernel was used and for the powertop test, new powertop 2.0 was used in F15, so at least these two tests are not comparable
14:08:42 <jskarvad> i will retest more and average results - it is also possible that the 0.5W is measurement error
14:09:14 <jskarvad> iirc the guy on phoronix mentioned much bigger numbers
14:11:13 <jskarvad> I will look more deep on it
14:12:54 <jskarvad> next: Fedora 15 power management guide
14:13:26 <jskarvad> there is F14 power management guide: http://docs.fedoraproject.org/en-US/Fedora/14/html/Power_Management_Guide/index.html
14:13:34 <jskarvad> that needs updating
14:14:25 <jskarvad> I added it on todo lsit and hopefully I will go through it during weekend
14:16:43 <jskarvad> I will post the text updates to power-management mailing list
14:19:04 <jskarvad> The text seems to be in good shape, it seems there will be  only needed updates to tuned, powertop and gnome power manager sections of this guide
14:22:36 <jskarvad> Last but not least: there is planned fedora 15 release party in Brno office on Tue, May 24, 06:00 PM
14:23:05 <jskarvad> if you will be near Brno, feel free to come
14:24:06 <jskarvad> there will be also very short talk (with demo :) regarding the PM news in F15
14:24:59 <jskarvad> that's all news for today
14:25:10 <jskarvad> opening space for free discussion
14:30:26 <jskarvad> any comments, questions, ideas?
14:32:25 <jskarvad> ok, thanks, that's all for today
